  Event ID 1120 & 1121 Reply Contact Every night I get the following event in my System event log.  There are always two of them, they have the same message but one comes in under Event ID  1120 and the other Event ID 1121.  I have tried restarting the www service, but it doesn't help. I can find no solution anywhere on the net. The World Wide Web Publishing Service failed to obtain site performance counters from HTTP.SYS.  The reported performance counters do not include counters from HTTP.SYS for this gathering.  The data field contains the error number.

  Re: Event ID 1120 & 1121 Reply Contact The error can be caused by HTTP.SYS is out of memory. Please check the HTTPERR.log file and find if there are some connection_refused and connection_abandoned_by_apppool errors. If there is, add EnableAggressiveMemoryUsage in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP\Parameters and restart HTTP and IIS services. Also check the boot.ini file and see if /3GB switch is enabled. Enabling /3GB switch will reduce the available NonPagedPool kernel memory for http.sys. You can remove the switch to test.
